Mar 13, · If your Active Directory domain controller fails and you have a DC backup (created using Windows Server Backup or other backup tools), you can restore a single domain controller or the entire AD mainaman.co this article, we will show you how to perform a non-authoritative AD DS recovery using Windows Server mainaman.co is assumed that you have a DC backup and you know the DSRM . Feb 21, · From the same console, go to Local Backup – Here you’ll see that there is no backup configured or no backup currently running for the local Domain Controller. Although you can also create an automatic scheduled backup to run daily or weekly at different hours, for this demonstration we are going to create a manual backup. The domain controller role is central to an Active Directory-based network. Learn how to protect your Windows Server domain controllers by using first-party backup tools.
In this post, you are going to learn how to do a Manual backup of an Active Directory domain controller. First, we are going to install the Windows Server Backup Feature, which is a new tool that started with Windows Server This feature is easy to use and can help you set up manual, scheduled, full, or custom AD backups.
If you have more than one, which is recommended for fail-over protection, backup at least one DC. You should back up AD with time intervals lower than 60 days; this is because, by default, the lifetime of AD tombstones are set to 60 days.
After the 60 days pass, the object disappears completely. If possible backup Active Directory every day. A handy tool to avoid restoring is the Active Directory Recycle Bin.
When you delete an object, it automatically goes to the Recycle Bin. So if you want to recover a particular object that you recently deleted, go to the bin and restore it. Keep 3 copies of your Backup — 2 Backups on Locally on different media hard-drives, etc and 1 Backup off-site on a remote server, or in the cloud.
Having no protection or backup strategy whatsoever could put the entire organization in danger — Believe it or not, Many small businesses don't regularly backup Active Directory. Make sure to have multiple domain controllers working together with fail-over functionalities and create a good backup and recovery strategy.
The Shadow Copy helps backup data on the volume even while applications that produce data are still running. It also allows the users to view the contents of shared folders as the content existed in previous points in time Snapshots.
The VSS Copy Backup on the other hand also does a full backup but preserves all the application files including logs on the system. This option is the preferred method for incremental backups, as it does not affect the sequence of backup. For the purpose of this demonstration, we are using a local hard disk to store the backup.
The backup should take some time depending on the size of the domain controller server. Once the backup is completed successfully, you can close the Backup Console. If you closed the Backup Wizard without waiting for the last message status, the backup will continue to run on the background. You can also confirm the status and completion results of the backup from the webadmin console or Windows Server Backup Feature. The console will display a message with information from this backup and others.
It will show the timestamp, type, and results. The main objective of this Active Directory backup demonstration was to manually store a copy of one of the two domain controllers on the local volume of the Windows server. The full backup will create a copy of all server data, including applications, OS files, and the system state. As already mentioned before in the Backup Recommendations section, always backup at least once a day and follow the rule. Also, remember always to have more than one domain controller running with fault-tolerance.
When one DC fails, the other one should take over. Although you can use third-party tools to run backups, the Windows Server Backup Feature comes for free as a bundled tool, and it is really easy to use. Active Directory is critical for any Windows environment. So as a best practice, it is recommended to perform full scheduled backups.

Step 2. For this lab, we are only going to change the Shadow Copy size limit configuration on the volume where we are going to store the AD database. Go back to Disk Management. This option will allow all the space available in the volume for the AD backup. Step 3. This feature can help you perform Active Directory database backups and restores. The way to install this feature is through the Server Manager.
Open the Server Manager console. Select your Local Server. Go to the Manage tab on the right upper-hand and click on the Add Roles and Features as seen in the image below.
